Material stream sink

sink Icon

This model should be used for boundary streams when additional information about the stream is desired.
Some of the additional informations calculated by this models are: * Mass density * Mass flow * Mass compostions * Specific volume * Vapour fraction * Volumetric flow * Liquid and Vapour compositions
